20 days agoIf I’m reading the part number right that regulator is rated for a current limit of 400mA At 5v that’s 2 watts.
If I’m reading the part number right that regulator is rated for a current limit of 400mA At 5v that’s 2 watts.
It helps ensure that levels between 2.5v and 5.5v can be fed to the controller without breaking anything. For some cheaper power supplies you might get a voltage drop when starting to pull load, this will clean that up and prevent the voltage from dropping too low for the microcontroller.
If I’m reading the correct datasheet I can see it is current limiting so it should shutdown when overdrawn.
